Detailed Description

template<int dim>
class aspect::Postprocess::VisualizationPostprocessors::GrainLagAngle< dim >

This postprocessor calculates and outputs the angle between the ~infinite strain axis and the velocity. Kaminski & Ribe (2002, Gcubed) call this quantity \(\Theta\) and define it as \(\Theta = \cos^{-1}(\hat{u}\cdot\hat{e})\) where \(\hat{u}=\vec{u}/|{u}|\), \(\vec{u}\) is the local flow velocity, and \(\hat{e}\) is the local infinite strain axis, which we calculate as the first eigenvector of the "left stretch" tensor. \(\Theta\) can be used to calculate the grain orientation lag parameter (GOL). Calculating GOL also requires the ISA rotation timescale ( \(\tau_{ISA}\)). GOL is not calculated within ASPECT right now because it is proportional to the spatial gradient of \(\Theta\), but in the future that calculation could be implemented in a material model with CopyOutputs (once they exist). By tracking \(\Theta\) as a CopyOutput (ie, a compositional field holding a calculated value that gets copied over instead of solved for), the spatial gradient of \(\Theta\) could be calculated for the previous timestep by obtaining the old solution for the input material model. That gradient, and also the time derivative of \(\Theta\), could then be used to calculate GOL at the previous timestep; \(\Theta\) could be updated at the current timestep; and both quantities could be stored in CopyOutputs to step forward in time. Basically, the calculation of GOL would have to lag one timestep behind the other quantities in order to get the gradients, but we're often interested in GOL in a steady-state flow anyway.

The function classes have to implement that want to output cell-wise data.

Returns

A pair of values with the following meaning:

The first element provides the name by which this data should be written to the output file.
The second element is a pointer to a vector with one element per active cell on the current processor. Elements corresponding to active cells that are either artificial or ghost cells (in deal.II language, see the deal.II glossary) will be ignored but must nevertheless exist in the returned vector. While implementations of this function must create this vector, ownership is taken over by the caller of this function and the caller will take care of destroying the vector pointed to.

Implements aspect::Postprocess::VisualizationPostprocessors::CellDataVectorCreator< dim >.
